Characteristics of Schottky Diode
- Low Turn-On voltage: The voltage required to turn on a Schottky diode is comparatively low as compared to other diodes.
- Low Forward Voltage Drop: Due to this property of diode it finds its application in Power Circuits because it is well adapted due to low voltage drop. This property also makes them best devices to be used in Power Rectifier Applications with high current density.
- Fast Recovery Time: Due to the semiconductor contact , Schottky diodes show a very fast recovery time making the circuits very fast. Thereby these diodes are used in Fast-Clamp Diode Applications where base junction is forward biased.
- Low Loss Energy: Schottky diode shows a very low energy loss even at higher frequencies. Due to this Schottky diodes are generally used in Solar Cells. Solar cells generally store energy and Schottky diodes prevents them from discharging.
Schottky Diode
The Schottky diode is popularly known as a hot-carrier diode, low-voltage diode, or Schottky barrier diode. It is a type of diode formed by the junction of a semiconductor with a metal. We know that in a PN junction diode, p-type and n-type semiconductors are joined collectively to form a PN junction. To the contrary, a Schottky diode replaces the p-type semiconductor with metals like aluminium.
Schottky diode has multiple characteristics which makes it a better choice over other diodes in the electronic industry. It displays characteristics like fast switching action and a low forward voltage drop. The symbolic representation of this diode, the construction of this diode, the energy band of the diode and what the V-I characteristic graph of this diode looks like.
